Description
:

The micro SD Memory Card is a small form factor non-volatile memory card which provides high capacity data storage. Its aim is to capture, retain and transport data, audio and images, facilitating the transfer of all types of digital information between a large variety of digital systems.

The Card has an internal intelligent controller which manages interface protocols, data storage and retrieval as well as hardware BCH Error Correction Code (ECC), defect handling, diagnostics and clock control. The advanced wear levelling mechanism assures an equal usage of the Flash memory cells to extend the life time. The hardware BCH-code ECC allows to detect and correct up to 40 defect bits per 1kByte. The controller performes control read operations and checks the consistence of the data. If an error of some bits is detected, the card refreshes all data in the flash cells to prevent data retention problems.

Optimized FW algorithms especially for high read access and long data retention applications

Patented power-off reliability technology

Wear Levelling technology

Equal wear levelling of static and dynamic data. The wear levelling assures that dynamic data as well as static data is balanced evenly across the memory. With that the maximum write endurance of the device is guaranteed

Write Endurance technology

Due to intelligent wear levelling an even use of the entire flash is guaranteed, regardless how much "static" (OS) data is stored.

Read Disturb Management

The read commands are monitored and the content is refreshed when critical levels have occurred

Auto Refresh for Data Retention enhancement

The interruptible background process maintain the user data for Read Disturb effects or Retention degradation due to high temperature effects

Near miss ECC technology

Minimize the risk of uncorrectable bit failure over the product life time. Each read command analyze the ECC margin level and refreshes data if necessary

Diagnostic features with Life Time Monitoring tool support

High reliability

Designed for industrial market especially read intensive application like navigation, infotainment, POS/POI, Medical and general boot medium use case:

Longevity, long life cycle, high data retention together with high temperature profile
